I show a tin for Tubes, Vent Sealing Percussion Large Mk111.
Black painted tin, soldered tear-seal Dimensions: 173x75x23mm High.
Made by B&S (Bullpit & Sons) and re-packed in Sydney.
These tubes were used by the Navy in 15", 13.5", 12" MkX1 & X11, 4" MkV11 & V111 Guns.
Brass case blackened all over. 0.5" at mouth, 0.525" at base and 2.185" (55.5mm) long.
Note that lot 232 matches this tin and is a converted Mk11 case to a Mk111.
I do not know why the label has the 10 blacked out and 4 stencilled unless only a part tin?
Mk11 tubes had perforated powder pellets . Mk111 had solid powder pellets. 4 rim notches.
Unfortunately the date part on the label is too hard to read. Possibly 1930’s?
